Rowley, Mass, assignors to United Shoe Machinery Corporation, Boston,Mass, a corporation of New Jersey Filed May 16, 1966, Ser. No. 550,212 7Claims. (Cl. 12-125) This invention relates to shoe machines and isherein illustrated as embodied in a machine for shaping the heel end ofan upper to a form and for wiping the lasting margin of the heel portionof the upper inwardly over and attaching said lasting margin to the heelend of an insole with adhesive, such for example as shown in US. LettersPatent No. 1,406,337, issued February 14, 1922, on an application tiledin the name of Matthias Brock, or No. 3,090,980, issued May 28, 1963, onan application filed in the name of James L. Forma. It will beunderstood, however, that in its broader aspects the invention is notlimited to embodiment in machines of the exact type disclosed in thementioned patents or to the particular mechanical construction hereinillustrated.

It is a principal object of this invention to provide novel and improvedmeans for contacting an insole placed on the heel form of. a machine ofthe type here under consideration thus to locate the heel end of theinsole on the form prior to the operation of the means for shaping theheel end of an upper to the form and the means for wiping the lastingmargin of the upper inwardly over and pressing it against the heel endof the ins-ole. With this purpose in view, and in accordance with afeature of the invention, the herein illustrated machine, which has asupport for a heel form mounted for movement from an inoperativeposition to an operative position, to clamp the heel end of an insole onthe form against a holddown, together with a heel band for shaping theheel end portion of an upper to the form and means for wiping thelasting margin of the upper inwardly over and for pressing it againstthe heel end of the insole, when the support is in its operativeposition, is provided with a pair of gauge members for contacting theinsole adjacent to its extreme heel end and a pair of gauge members forcontacting the insole adjacent to the heel breast line and toewardly ofthe heel seat.

More particularly, and in accordance with other features of theinvention, the gauge members which contact the insole adjacent to thebreast line are carried by a pair of arms pivotally mounted on thesupport adjacent to the heel form and interconnected for equalizingmovements toward and away from the opposite sides of an insole placed onthe form and means are provided for yieldingly urging the gauge memberstoward the insole, while the gauge members which contact the insoleadjacent to its extreme heel end comprise a pair of fingers pivotallymounted on a (fixed part of the machine and adapted yieldingly to engagethe extreme heel end of the form of. an insole thereon, when the supportis in its inoperative position and to be withdrawn from operativeposition as the support is moved to clamp the insole against theholddown. Preferably, and as herein illustrated, these fingers arejoined by an arcuate web portion adapted to engage the heel end of theupper at its top line, as the support is moved downwardly after theupper has been shaped to the form by the heel band and its lastingmargin wiped inwardly and pressed against the heel end of the insole bythe wipers, thereby to lift the assembled upper and insole off of theheel form.

The above and other objects and features of the invention will appear inthe following detailed description of Patented Jan. 31, 1967 thepreferred embodiment illustrated in the accompany ing drawings and willbe pointed out in the claims.

In the drawings,

FIG. 1 is a view in side elevation of a portion of a shoe machine inwhich the novel features of this invention have been embodied;

FIG. 2 is a plan view at an enlarged scale of a portion of the machineshown in FIG. 1;

FIG. 3 is a view in front elevation, also at an enlarged scale, of apart of the machine shown in FIG. 2;

FIG. 4 is a view in side elevation similar to that of FIG. 1, but withportions of the machine omitted and showing an intermediate step in theoperation of the machine;

FIGS. 5 and 6 are views like that of FIG. 4 but showing subsequent stepsin the operation of the machine;

FIG. 7 is a perspective view of a shoe upper and insole after the heelend of the upper has been shaped and its lasting margin secured to theheel end of the insole.

Referring to these drawings, and particularly FIG. 1, the machine whichis partially illustrated therein is similar to a portion of the machineshown and claimed in US. Letters Patent No. 3,138,810, issued June 30,1964, on an application filed in the name of Karl V. Becker, seeespecially FIG. 2 of the drawings of that patent. As is explained indetail in the aforementioned patent, this ma chine is provided forshaping the heel end portions of the upper materials of a shoe. Thus,the illustrated mechanism includes an end embracing the heel band 20 andwiping means, identified generally by the reference character 22, seeFIG. 5, which are similar to the wiping means of the Becker patent, seeFIGS. 4 and 5 of that patent. The heel band and wiping means areassociated with a frame construction, indicated generally by thereference character 24, and are operated by mechanisms not here shown,but which are similar to a function in the same manner as thecorresponding mechanisms of the Becker patent to which reference may bemade. In this connection, however, it is pointed out that the heel band20 is moved from the inoperative postion in which it is shown in FIG. 1to the operative position of FIG. 5 by means of a fluid pressureactuated piston connected to the triangular shaped lever 26 which inturn is connected to a carriage 28, slidably mounted on the frame 24 andon which the heel band is carried. Also, the wipers, which are mountedon and actuated by cam mechanism associated with the carriage (whichcorresponds to the carriage 114 of the Becker patent) are operated by afluid pressure actuated piston, not shown, which corresponds to thepiston contained in the cylinder 142 of the machine of the Beckeripatent.

As distinguished from the machine of the Becker patent, in which theupper materials are shaped to the heel end of a last and their lastingmargins wiped inwardly over the heel end of an insole mounted on thebottom of the last, the herein illustrated machine is intended forso-called oif-the-last work wherein the heel end of the upper materialsis shaped to a heel form. Also, the machine of the Becker patent isprovided with means for driving a tack to secure the overwiped lastingmargin to the insole. However, in the machine of this invention, thelasting margin is adhesively secured to the heel end of an insole on theheel form by means of adhesive previously applied to the insole.Adhesion results from the wiping and pressing action of the wipingmeans.

Accordingly, in place of the usual last pin there is mounted on theupper end of a jack post 30, slidably mounted on the front portion ofthe machine frame 24 and corresponding to the jack post 26 of themachine described in the Becker patent, a holder block 32 adapted toreceive a heel form 34. This heel form, which may be made of wood, metalor any other suitable material, is of a shape corresponding to the shapeof the heel end of a last and has a base plate 36 and a dovetail portion38, by means of which it is removably mounted on the block 32. One endof this dovetail portion abuts against a stop surface, not shown, on theblock 32, when the form is in the position shown in the drawings, andthe form may be removed from the block 32 by sliding movement to theright, after the block itself has been removed from the jack post.

Directly above the jack post and the heel form thereon, there issupported on the frame 24 a holddown mem ber 41), corresponding to theholddown 48 of the machine of the Becker patent. For elevating the jackpost 30, thereby to cause an insole I on the heel form to be clamped inposition thereon by engagement with the h-olddown, a piston, not shown,corresponding to the piston in the cylinder 44 of the machine of theBecker patent, is connected to the lower end of the jack post.

For locating the insole I on the form 34, in proper aligned positionthereon, prior to the elevation of the jack post 30, two sets of gaugemembers are provided. The first set of gauge members comprise a pair ofmembers 50, 50 each adjusta-bly mounted on the upper end of a rod 52,see especially FIG. 3. One of these rods is carried by a first bellcrank lever d, pivotally mounted by means of a screw stud 55 on aupturned portion of the base plate 36, while the other rod is carried bya second and similar bell crank lever 58, pivotally mounted by means ofa screw stud 60 to another upturned portion of the plate 36. Secured toeach of the members 50 is a gauge member 70 shaped as shown in FIGS. 3and 4 and having an upstanding finger-like portion 72 and a rearwardlyextending portion 74, the upper part 76 of which is bent inwardly at anangle, see FIG. 3. Adjacent to the upper edge of the inner end of theform 34 are two cutaway portions providing abutment surfaces 80, 8%)against which the rearwardly extending portions 74, 74 of the members 7670 are yieldingly held by the action of a coil spring 82, stretchedbetween the bell crank levers 54 and 58, FIG. 3. Secured to the bellcrank lever 58 is a pin 86 which extends forwardly through a slot 88 inthe bell crank lever 54, thus providing for equalizing movements ofthese bell crank levers and of the gauge members 70, 70 carried thereby.Also, by lifting this pin with his finger, as indicated in FIG. 6, theoperator of the machine can separate the gauge members thus to releasethe insole in a manner and for a purpose to be explained below.

The second set of gauge members comprises a pair of fingers 9t), 90formed of resilient material and joined by an arcuate web portion 91 asshown in FIGS. 1 and 2. These fingers are secured, by means of screws92, 92 to the opposite sides of a supporting block 94 which is pivotallymounted on the machine frame 24 by means of a pin 93. When the jack postis in its lowermost position, FIG. 1, a spring 95 urges these fingersyieldingly into engagement with the heel form in two locations,approximately 90 apart around the generally circular heel end of theform, FIG. 2, when the jack is in its lowermost position. As can be seenin FIG. 1, these fingers extend slightly above the upper surface of theheel form so as to serve as gauge members against which the heel end ofthe insole I may be engaged to position the heel end of the insole onthe form. At their upper ends, the fingers 90, 90 are turned outwardlyto provide flanges 96, 96. A stop screw 97 limits pivotal movement ofthe block 94, as shown in FIGS. 4 and 5, when the jack is elevated.

In using the herein illustrated machine, the operator first suspends aclosed shoe upper U on the h-olddown member 48, in the mannerillustrated in FIG. 1, and then places an insole Ion the heel form 34,locating the insole on the form, at the breast line by means of the twogauge members 70, 70 and at the extreme heel end by means of the twogauge members 94 90, see FIGS. 2 and 3. To facilitate the placing of theinsole on the heel form, the operator may first separate the gaugemembers 70, 70 by slightly elevating the pin 86, then after the insolehas been brought into engagement with the two gauge members 9t 96, byreleasing the pin the operator causes the members 70, 70 to return tothe positions shown in FIG. 3, thus causing the upstanding portions 72,72 to position the insole adjacent to the breast line. As the gaugemembers 70, '70 return to the positions shown in FIG. 3, the inturnedportions 76, 76 will engage and hold the insole down against the uppersurface of the heel form.

Next, the operator will cause the jack post to be moved upwardly bydepressing a treadle, not shown, which actuates a control valve,corresponding to the control valve 4%? of the machine of the Beckerpatent. Actuation of this valve and the resulting upward movement of thejack post causes the insole to be clamped firmly against the heel formas shown in FIG. 4. Just before the operator steps on the treadle, hewill grasp the upper U and hold it in a position out of the way of theheel form as the latter is caused to move upwardly. As the jack postmoves upwardly, the insole will be held in proper position by the gaugemembers 70, 70

The operator will now place the upper on the heel form and shift itaround, laterally and heightwise, to put it in the proper position inwhich it will be retained as a result of a lengthwise pull exertedthereon by the operator, see FIG. 4. While still exerting this pull onthe upper the operator will release the treadle thus causing the controlvalve, corresponding to valve 407 of the Becker patent to be shiftedback to its original position by means of a spring. As a result of thisreturn of the control valve and in a manner explained in detail in theBecker patent, the upper shaping elements, i.e., heel band 20 and wipingmeans 22, will be caused to operate in an automatic cycle during whichthe heel band is first advanced to shape the upper around the heel endof the form and then the wipers are advanced and closed to wipe thelasting margin of the upper inwardly over and to press the lastingmargin firmly against the bottom of the insole, as shown in FIG. 5.

As a result of this action of the wipers, the lasting margin is securedto the insole in lasted position by the adhesive previously applied tothe insole. As the automatic operating cycle of the machine is nowcompleted, with the tack driving step omitted in view of the use ofadhesive for securing the lasting margin to the insole, the heel band isretracted together with the wiping means and the jack post is returnedto its original position. While the jack post is moving downwardly, theweb portion 91 which is yieldingly held against ,the heel end of theform 34 by the action of spring will engage and lift the now combinedupper and insole oit of the form, see FIG. 6, this action beingfacilitated by the operator who lifts the pin 88 slightly and justenough to swing the two gauge members 70', 74 away from the insole torelease the insole from the action of the inturned end portions 76, 76.Finally, the operator entirely removes the completed assemblage of anupper and insole, see FIG. 7, from the machine, thus making it ready foroperation on the next insole and upper.
